Scientists see energy gap modulations in a cuprate superconductor

For years physicists have been trying to decipher the electronic details of high-temperature superconductors. These materials could revolutionize energy transmission and electronics because of their ability to carry electric ...

Surfing the waves: Electrons break law to go with the flow

If you see people walking down a street and coming to a junction, it's difficult to predict which direction they might take. But, if you see people sitting in separate boats, floating down a stream, and the stream splits ...

The power of attraction: Magnets in particle accelerators

In 1820, Hans Christian Oersted gave a demonstration on electricity to a class of advanced students at the University of Copenhagen in Denmark. Using an early battery prototype, he looked to see what effect an electric current ...

Electric current

Electric current is the rate of flow of electric charge. The electric charge that flows is carried by, for example, mobile electrons in a conductor, ions in an electrolyte or both in a plasma.

The SI unit of electric current intensity is the ampere. Electric current is measured using an ammeter.
